Abstract

Studies on classification of national roads have been continued, but there is little research on the classification of urban arterial roads. Due to the increase of traffic volume, urban arterial roads do not perform well as main roads. In this paper, the function of urban arterial road was established by using cluster analysis using traffic characteristics. Traffic characteristics such as traffic volume, weekend coefficient and speed coefficient were used to establish the functions of 55 main arterial roads in Seoul. The results of this paper are compared with those of the method using AADT. The method using AADT classifies the characteristics according to the traffic volume of the whole lane. In this paper, however, the results are derived using the traffic volume per lane reflecting the actual traffic volume. In addition, the functional classification of the arterial roads in Seoul was compared with the results of this paper to verify that the traffic characteristics were reflected. As a result, the method presented in this paper is more effective in showing traffic characteristics than the current highway functional classification method, and the functional classification system will be helpful for road extension and planning design.

국도의 분류에 대한 연구는 계속되어왔으나 도시간선도로의 분류에 대한 연구는 미진한 편이다. 교통량의 증가로 도시간선도로는 간선도로로서의 역할을 제대로 수행하지 못하고 있다. 본 논문에서는 교통특성변수를 사용한 군집분석을 이용하여 도시간선도로의 기능을 정립하였다. 서울시내 55개의 간선도로의 기능을 정립하기 위해 교통량, 주말계수, 속도 계수 등 교통특성을 사용하였다. 본 논문의 결과와 AADT를 사용한 방법의 결과를 비교하였는데 AADT를 사용한 방법은 전체 차선의 교통량에 의해 특성을 분류하였으나 본 논문에서 실제 교통량을 반영한 차선당 교통량을 주요 변수로 사용하여 결과를 도출하였다. 또한 서울시 간선도로 기능분류와 본 논문의 결과를 비교하여 교통특성이 반영되었음을 증명하였다. 결과적으로 본 논문에서 제시한 방법은 현재 간선도로 기능분류 방법보다 교통특성을 나타내는데 효과적이며 기능분류체계는 도로확장 및 계획 설계에 도움이 될 것으로 판단된다.
